bonsoir à tous!

j'explique mon problème:

J'ai un serveur sme 7.2 sur lequel j'ai configuré samba, j'ai un partage public qui est monté sur une dizaine de machines grâce à la commande smbmount.
Les machines accèdent plus ou moins à ce partage.
J'ai remarqué qu'une machine en particulier accèdent beaucoup au partage (il est monté dans /usr/local).
Cette machine perd la connexion au partage plusieurs fois par jour, aujourd'hui 2 fois hier 5-8 fois.
Je n'arrive pas à déterminer pourquoi... quand cette machine a perdu l'accès je suis obligé de demonter (umount) puis de remonter le partage (smbmount),les autres machines continuent d'avoir accès je peut lister les partages etc... mes machines clientes sont des Red Hat EL 4 et j'ai 2 centos 5.
Le problème intervient sur une machine Red Hat...
Cette machine accèdent beaucoup au partage et demande beaucoup de ressources processeur (est ce une piste???) y a t il des bloquages au niveau samba par rapport aux accès au partage?

je poste mon fichier de conf samba et mes fichiers de log:
